CROSS-REFERENCE TO RELATED APPLICATION

This application claims the priority benefit of the earlier filing date of U.S. Provisional Patent Application No. 62/486,925, filed Apr. 18, 2017, which is hereby specifically incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates to the field of footwear. More particularly, the present disclosure relates to a sandal with detachable upper.

BACKGROUND

The background description provided herein is for the purpose of generally presenting the context of the disclosure. Unless otherwise indicated herein, the materials described in this section are not prior art to the claims in this application and are not admitted to be prior art by inclusion in this section.

As footwear styles change, different designs of sandals go in and out of style. For legacy sandals with straps or strap assemblies permanently affixed to the soles of the sandals, the only way to keep up with the changing styles of sandals was to buy a new pair of sandals. This often resulted in the old pair of sandals that went out of style being discarded. Further, if either of the strap/strap assemblies or the sole of the sandal became damaged, the entire sandal would need to be discarded. These issues often resulted in functional sandals or portions of sandals ending up in landfills and contributing to growing pollution issues.

FIG. 1 illustrates a top view of an example shoe 100, according to various embodiments. The shoe 100 may be a sandal, wherein the sandal may comprise an openwork upper, straps, and/or strap assemblies. The openwork upper, straps, and/or strap assemblies may be utilized for securing the shoe 100 to a foot of a wearer. The shoe 100 may have a toe 112 located at one end of the shoe 100 and a heel 114 located at an opposite end of the shoe 100. When worn, toes of the wearer may be located toward the toe 112 of the shoe 100 and a heel of the wearer may be located toward the heel 114 of the shoe.

The shoe 100 may include a sole 102. A foot of the wearer may be located on a top side 106 of the sole 102 when the shoe is worn. The sole 102 may be shaped to extend under an entirety of the foot of the wearer. Accordingly, the sole 102 may be located between the foot of the wearer and a surface on which the wearer is standing when the shoe 100 is being worn. The sole 102 may extend from the toe 112 of the shoe 100 to the heel 114 of the shoe 100.

The sole 102 may include a midsole 104 and an outer sole (see outer sole 204 of FIG. 2). The midsole 104 may extend along the top side 106 of the sole 102 and may be directed toward the foot of the wearer when the shoe 100 is worn. In particular, the foot of the wearer may contact the midsole 104 when the shoe 100 is worn and the wearer is standing on a surface.

The midsole 104 may be formed of a material that provides cushioning for the foot of the wearer. In some embodiments, the midsole 104 may be formed of a foam, such as ethylene vinyl acetate (EVA), polyurethane, or some combination thereof. Further, in some embodiments, the midsole 104 may be contoured based on the shape of the foot of the wearer and/or may be ergonomically designed to absorb shock, provide arch support, and/or maintain the foot of the wearer in a proper anatomical position.

The midsole 104 may have a first recess 108 and a second recess 110. In the illustrated embodiment, the first recess 108 and the second recess 110 extend into the midsole 104 from a top surface 133 of the midsole 104. In other embodiments, the first recess 108 and the second recess 110 may extend into the midsole 104 from any exposed surface of the midsole 104, including the top surface 133 of the midsole, a first side surface 116 of the midsole 104, a second side surface 118 of the midsole 104, a bottom surface of the midsole 104 (the bottom surface opposite to the top surface 133), or some combination thereof.

The first recess 108 and the second recess 110 may extend into the midsole 104 in locations that are closer to the heel 114 of the shoe 100 than to the toe 112 of the shoe 100. Further, the first recess 108 may extend into the midsole 104 at a location toward the first side surface 116 of the midsole 104 and the second recess 110 may extend into the midsole 104 at a location toward the second side surface 118 of the midsole 104. In particular, the location where first recess 108 extends into the midsole 104 may be closer to the first side surface 116 than to the second side surface 118, and the location where the second recess 110 extends into the midsole 104 may be closer to the second side surface 118 than to the first side surface 116.

The first recess 108 and the second recess 110 may be elongated. For example, the first recess 108 and the second recess 110 may be elongated in directions substantially (within 10 degrees) parallel to a length of the shoe 100, the length of the shoe 100 extending between the toe 112 of the shoe 100 and the heel 114 of the shoe, thereby bisecting the sole 102. In particular, a length 122 of the first recess 108 may be greater than a width 124 of the first recess 108 and a length 126 of the second recess 110 may be greater than a width 128 of the second recess 110. Further, the first recess 108 and the second recess 110 may be elongated in a same direction or in directions within 20 degrees of each other. While the first recess 108 and the second recess 110 are shown having a straight elongation in the illustrated embodiment, it is to be understood that either or both of the first recess 108 and the second recess 110 may have a curved elongation in other embodiments.

The sole 102 may further have an aperture 130 that extends through the midsole 104. In particular, a first end of the aperture 130 may be located at the top surface 133 of the midsole 104 and may extend past the bottom surface of the midsole 104 (the bottom surface opposite to the top surface 133). The aperture 130 may extend through an entirety of the sole 102, which may include both the midsole 104 and the outer sole.

The aperture 130 may extend into the midsole 104 in a location that is closer to the toe 112 of the shoe 100 than to the heel 114 of the shoe 100. Further, the location that the aperture extends into the midsole 104 may be located toward a midpoint between the first side surface 116 of the midsole 104 and the second side surface 118 of the midsole 104, or closer to the first side surface 116 of the midsole 104 than to the second side surface 118 of the midsole 104. In particular, the aperture 130 may be positioned such that the aperture 130 is to be located between a big toe and other toes of the wearer when the foot of the wearer is positioned on the sole 102 as intended. Further, a distance between the aperture 130 and the first side surface 116 of the midsole 104 may be greater than a distance between the first recess 108 and the first side surface 116 of the midsole 104, and a distance between the aperture 130 and the second side surface 118 of the midsole 104 may be greater than a distance between the second recess 110 and the second side surface 118 of the midsole.

The aperture 130 may be elongated. For example, the aperture 130 may be elongated in a direction substantially (within 10 degrees) parallel to the length 120 of the shoe 100, the length 120 of the shoe 100 extending between the toe 112 of the shoe 100 and the heel 114 of the shoe, thereby bisecting the sole 102. In particular, a length of the aperture 130 may be greater than a width of the aperture 130. While the aperture 130 is shown having a straight elongation in the illustrated embodiment, it is to be understood that the aperture 130 may have a curved elongation in other embodiments.

The shoe 100 may further include a strap assembly 132. The strap assembly 132 may be removably secured to the sole 102. In particular, the strap assembly 132 is illustrated in a secured configuration in the illustrated embodiment. For example, portions of the strap assembly 132 may extend and be secured within the first recess 108, the second recess 110, and/or the aperture 130 as is described further throughout this disclosure. Further, the strap assembly 132 may be removed from the sole 102, as is described further throughout this disclosure.

In the illustrated embodiment, the strap assembly 132 may include a first strap 134 and a second strap 136. The first strap 134 may extend between the aperture 130 and the first recess 108. A first portion of the first strap 134 may be secured within the aperture 130 via a post of the strap assembly 132 and a second portion of the first strap 134 may be secured within the first recess 108 via a first anchor of the strap assembly 132 as described further throughout this disclosure. The second strap 136 may extend between the aperture 130 and the second recess 110. A first portion of the second strap 136 may be secured within the aperture 130 via the post of the strap assembly 132 and a second portion of the second strap 136 may be secured within the second recess 110 via a second anchor of the strap assembly 132 as described further throughout this disclosure. While the strap assembly 132 is illustrated including two straps in the illustrated embodiment, it is to be understood that the strap assembly 132 may include additional straps (such as straps that extend between the first strap 134 and the second strap 136, and/or straps to secure to an ankle of the wearer when the shoe 100 is worn), additional material (such as flexible material including cloth, cotton, leather, flexible rubber, flexible plastic, other similar flexible materials, or some combination thereof) that are coupled to the first strap 134 and/or the second strap 136, material in lieu of the straps that is secured within the aperture 130, the first recess 108, and the second recess 110, or some combination thereof.

The illustrated embodiment illustrates a single shoe 100 of a pair of shoes. In particular, the shoe 100 illustrated may be configured to be worn on a left foot of a wearer. The pair of shoes may further include a second shoe that is configured to be worn on a right foot of the wearer. The second shoe that is configured to be worn on a right foot may be a mirror reflection of the shoe 100 about the first side surface 116 of midsole 104. Accordingly, it is to be understood that the second shoe may include the same features of the shoe 100, but mirrored.

FIG. 2 illustrates a bottom view of the example shoe 100 of FIG. 1, according to various embodiments. In particular, FIG. 2 may illustrate a bottom side 202 of the sole 102, wherein the bottom side 202 is located opposite to the top side 106 (FIG. 1) of the sole 102.

The outer sole 204 may extend along the bottom side 202 of the sole 102. The outer sole 204 may contact a surface when the shoe 100 is worn. In particular, a bottom surface 208 of the outer sole 204 may contact a surface when the shoe 100 is worn. For example, the bottom surface 208 of the outer sole 204 may contact a surface when a wearer of the shoe 100 is standing on the surface.

The outer sole 204 may be affixed to the midsole 104 (FIG. 1). In particular, midsole 104 may be affixed at the bottom surface of the midsole 104 (the bottom surface of the midsole 104 being opposite to the top surface 133 of the midsole 104) to a top surface of the outer sole 204 (the top surface of the outer sole 204 being opposite to the bottom surface 208 of the outer sole 204). In some embodiments, the midsole 104 may encircle a portion of the outer sole 204. In other embodiments, the midsole 104 may be entirely located above the top surface of the outer sole 204.

The outer sole 204 may be formed of a material that is to resist wear to the outer sole 204 and/or to provide traction to a surface when the shoe 100 is worn. The outer sole 204 may be formed of a different material than the midsole 104. In other embodiments, the outer sole 204 and the midsole 104 may be formed of the same material. In some embodiments, the outer sole 204 may be formed of rubber, polyurethane, polyvinyl chloride (PVC), or some combination thereof. The outer sole 204 may be formed of a different material than the midsole 104. In other embodiments, the outer sole 204 and the midsole 104 may be formed of the same materials. Further, in some embodiments, the outer sole 204 may be contoured to provide traction to a surface when the shoe 100 is worn.

The strap assembly 132 (FIG. 1) may include a post 206. The post 206 may be located adjacent to the bottom surface 208 of the outer sole 204. In some embodiments, the bottom surface 208 of the outer sole 204 may have an indentation to receive the post 206, such that the bottom surface 208 is aligned with a bottom of the post 206 and/or extends past the bottom of the post 206.

The post 206 may further be located adjacent to the aperture 130 (FIG. 1). The post 206 may be coupled to the first strap 134 (FIG. 1) and the second strap 136 (FIG. 1), and may secure a portion of the first strap 134 and a portion of the second strap 136 within the aperture 130. For example, the post 206 may be shaped and/or sized such that the shape and/or size of the post 206 may prevent the post 206 from passing through the aperture 130. In the illustrated embodiment, the post 206 is circular, although it is to be understood that the post 206 may be any other shape and/or size that prevents the post 206 from passing through the aperture 130.

FIG. 3 illustrates a side view of the example shoe 100 of FIG. 1, according to various embodiments. As illustrated in FIG. 3, the midsole 104 may be affixed on top of the outer sole 204. In particular, the midsole 104 may be located at a top side 106 of the sole 102 and the outer sole 204 may be located at a bottom side 202 of the sole 102.

The sole 102 may be relatively flat with the top surface 133 of the midsole 104 being substantially (within 10 degrees) parallel to the bottom surface 208 of the outer sole 204. Further, a thickness 302 of the sole 102 at a toe 112 of the shoe 100 may be substantially (within 5 centimeters) the same as a thickness 304 of the sole 102 at the heel 114 of the shoe 100. In other embodiments, the sole 102 may be shaped differently than the illustrated embodiment. For example, the sole 102 may be wedge-shaped in some embodiments, where the thickness 304 at the heel 114 is greater than the thickness 302 at the toe 112. In other embodiments, the sole 102 may be shaped similar to legacy high heel shoes, where the thickness 302 at the toe 112 is a first thickness, with a majority of the sole 102 having the first thickness, and the thickness 304 at the heel 114 being greater than the first thickness, resulting in a portion of the bottom surface 208 of the outer sole 204 being located above a surface when the shoe 100 is positioned on the surface.

The strap assembly 132 may extend above the top surface 133 of the midsole 104. In particular, a portion of the strap assembly 132 may be located off of the top surface 133 of the midsole 104 absent external forces (other than gravity) being applied to the strap assembly 132. The strap assembly 132 may be pre-formed to retain the illustrated shape when the strap assembly 132 is secured to the sole 102 and absent the external forces.

FIG. 4 illustrates a top view of an example sole 400, according to various embodiments. In particular, the sole 400 is illustrated separate from a strap assembly that may be secured to the sole 400. The sole 400 may be implemented in the shoe 100 (FIG. 1) and may include one or more of the features of the sole 102 (FIG. 1). For example, the sole 400 may include a midsole 402 that includes one or more of the features of the midsole 104 (FIG. 1). Further, the midsole 402 may have a first recess 404, a second recess 406, and an aperture 408 that include one or more of the features of the first recess 108 (FIG. 1), the second recess 110 (FIG. 1), and the aperture 130 (FIG. 1), respectively.

The first recess 404 may be of a length 410 and a width 412. The length 410 may be greater than the width 412, resulting in the first recess 404 being elongated. The second recess 406 may be of a length 414 and a width 416. The length 414 may be greater than the width 416, resulting in the second recess 406 being elongated. The length 410 of the first recess 404 may be equal to the length 414 of the second recess 406 and the width 412 of the first recess 404 may be equal to the width 416 of the second recess 406. In other embodiments, the length 410 and/or the width 412 of the first recess 404 may be different than the length 414 and/or the width 416 of the second recess 406, respectively.

The length 410 of the first recess 404 and the length 414 of the second recess 406 may vary as the first recess 404 and the second recess 406 extend into the midsole 402. For example, the length 410 of the first recess 404 and the length 414 of the second recess 406 may increase as the first recess 404 and the second recess 406 extend into the midsole 402. The length 410 of the first recess 404 may abruptly increase as the first recess 404 extends into midsole 402, resulting in a first portion of the first recess 404 toward a top surface 422 of the midsole 402 being a first length and a second portion of the first recess 404 farther away from the top surface 422 of the midsole 402 being a second length that is greater than the first length. The length 414 of the second recess 406 may abruptly increase as the second recess 406 extends into midsole 402, resulting in a first portion of the second recess 406 toward a top surface 422 of the midsole 402 being a first length and a second portion of the second recess 406 farther away from the top surface 422 of the midsole 402 being a second length that is greater than the first length.

The width 412 of the first recess 404 and the width 416 of the second recess 406 may be substantially (within 1 centimeter) uniform as the first recess 404 and the second recess 406 extend into the midsole 402. In other embodiments, the width 412 of the first recess 404 and the width 416 of the second recess 406 may increase or decrease as the first recess 404 and the second recess 406 extend into the midsole 402. For example, the width 412 of the first recess 404 may abruptly increase as the first recess 404 extends into midsole 402, resulting in a first portion of the first recess 404 toward a top surface 422 of the midsole 402 being a first width and a second portion of the first recess 404 farther away from the top surface 422 of the midsole being a second width that is greater than the first width. The width 416 of the second recess 406 may abruptly increase as the second recess 406 extends into midsole 402, resulting in a first portion of the second recess 406 toward a top surface 422 of the midsole 402 being a first width and a second portion of the second recess 406 farther away from the top surface 422 of the midsole being a second width that is greater than the first width.

The aperture 408 may have a length 418 and a width 420. The length 418 of the aperture 408 may be less than the length 410 of the first recess 404 and may be less than the length 414 of the second recess 406. In other embodiments, the length 418 of the aperture 408 may be equal to or greater than the length 410 of the first recess 404 and may be equal to or greater than the length of the second recess 406.

The width 420 of the aperture 408 may be greater than the width 412 of the first recess 404 and may be greater than the width 416 of the second recess 406. For example, the width 420 of the aperture 408 may be twice the width 412 of the first recess 404 and may be twice the width 416 of the second recess 406. In other embodiments, the width 420 of the aperture 408 may be more than twice the width 412 of the first recess 404 and may be more than twice the width 416 of the second recess 406. In other embodiments, the width 420 of the aperture 408 may be equal to or less than the width 412 of the first recess 404 and may be equal to or less than the width 416 of the second recess 406.

FIG. 5 illustrates a bottom view of the example sole 400 of FIG. 4, according to various embodiments. The sole 400 may include an outer sole 502. The outer sole 502 may include one or more of the features of the outer sole 204 (FIG. 2). For example, the outer sole 502 may include the aperture 408 and an indentation 504 that include one or more of the features of the aperture 130 (FIG. 1) and the indentation described in relation to FIG. 2, respectively.

The aperture 408 may have a length 506 and a width 508. The length 506 of the aperture 408 toward the bottom surface 510 of the outer sole 502 may be the same length as the length 418 of the aperture 408 toward the top surface 422 (FIG. 4) of the midsole 402 (FIG. 4). In other embodiments, the length 506 toward the bottom surface 510 may be greater than or less than the length 418 at the top surface 422. Further, the width 508 of the aperture 408 toward the bottom surface 510 of the outer sole 502 may be the same width as the width 420 of the aperture 408 toward the top surface 422 of the midsole 402. In other embodiments, the width 508 toward the bottom surface 510 may be greater than or less than the width 420 toward the top surface 422.

The indentation 504 may extend into the outer sole 502 from the bottom surface 510 of the outer sole 502. In some embodiments, the indentation 504 may further extend into the midsole 402. The indentation 504 may encircle the aperture 408. The indentation 504 may have a perimeter that is the same shape as a perimeter of a post of a strap assembly (such as the post 206 (FIG. 2)). When a strap assembly (such as the strap assembly 132 (FIG. 1)) is secured to sole 400, the post of the strap assembly may be located within the indentation 504.
